UNITED STATES PATENT PHILIP LINDEMEYR, OF BALTIMORE, MARYLAND, ASSIGNOR TO THE MONAROH MANUFACTURING COMPANY OF BALTIMORE CITY.

MACHINE FOR CAPPING BOTTLES.

SPECIFICATION forming part of Letters Patent No. 603,107, dated April 26, 1898. Application filed October 25, 1897. Serial No. 656,299. (No model.)

To ctZZ whom it may concern:

Be it known that I, PHILIP LINDEMEYR, a resident of Baltimore, in the State of Maryland,-have in vented certain new and useful Improvements in Machines for Capping Bottles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and use the same.

The invention relates to machines for capping bottles; and it has for its object to fasten capsv upon bottles by simple and efficient mechanism.

The invention consists in the construction hereinafter described and pointed out.

In the accompanying drawings, Figure 1 is a side elevation of the improved machine, partly in section. Fig. 2 is a partial enlarged section of a bottle-head, metal cup or die, and cap, and capsecuring tools in operative position.

Numeral 1 denotes the base of the machine stand or frame, and 2 its frame-post or pedestal, which is preferably tubular.

3 denotes a bottle-supporting platform or table forming part of the frame. This is provided with a seat 4 to receive the bottom of a bottle.

Above the table 3 extend posts 5,wl1ich support a cross-plate 6, having an opening 710 receive a movable hollow plunger 8. The plunger is fixed to a cross-bar 9, attached to rods 10, movable through guides 11 and 12.

The lower ends of rods 10 are connected by a cross-bar 13, to which at it is connected a rod 15, the foot of which is connected to a treadle-lever 16. This lever 16 has its fulcrum between lugs 17 on the base, between which lugs it is loosely supported by a pivot 18. The base is slotted to receive the lever.

19 is the foot-piece of the lever, and 20 an adjustable stop therefor.

W'ithin the hollow .plunger 8 is a spring 21, bearing on a disk or plate 22, which has a pendent stem 23, supporting an inverted cup or die 24, adapted to fit, approximately, the head of a bottle. This cup 24 is adapted to act as a die and form (in whole or in part) a cap from metal foil or other thin metal simultaneously with pushing it upon the bottlehead.

25 are openings in the sides of the cup or die for the passage of reciprocating tool-bars 26. These are movably supported in the frame-posts and are normally held by springs 27 at a little distance from the head of a bottle placed on table 8, as indicated in Fig. 1.

28 are cams on rods 10, adapted to push in- Wardly the sliding bars 26 to the position illustrated in Fig. 2.

29 are springs which are compressed by the rods 10 when pulled down by the treadlelever. When pressure is removed from said lever, the springs lift the rods and the connecting cross-bars and also the plunger 8 and the cup 24, and thereupon springs 27 retract tools 26.

The machine, though not limited as to use thereby, is primarily intended to fasten or look caps such as shown upon bottle-heads having a suitable groove or equivalent depressions. These caps have their flanges divided into two or more parts or fingers 30, which, or a part of which, are bent into the groove or depressions, with the effect to fasten the caps on the bottle-heads. Abottle is first suitably seated on the-table in seat 4 and amp placed over its mouth. Thereupon the treadle is lowered and the die 24. drawn down upon the cap by means of the rods 10 and plunger8. The spring 21 guards against overpressure and injurious concussion. At the moment the cap is pressed upon the bottlehead the tools 26 are forced inwardly by cams 2S, and the flange-fingers, or a part of them, are forced into engagement with the bottlehead. The springs 27 are compressed by the inward movement of the tools and serve to guard the bottle against dangerous pressure, as well as to return the tools.

It has usually been customary in machines intended to bend the flanges of caps upon bottle-necks to surround the entire flange with a continuous series of bending-tools to avoid the buckling of the metal. This has involved the bending or swagin g of the entire circumference of the flange and the use of complicated devices and considerable power. By the present improvement the cap is held immovably upon the bottle-mouth and against its neck, and thebending-tools are applied only at points Widely separated from each other, the die having openings for the passage of the tools, by which means the buckling of the cap-flange and the use of unnecessarily complex tool-operating devices are avoided, it being sufficient for practical purposes that the cap-flange be indented to engage in a depression or under a shoulder in the neck at two diametrically opposite points only; and, further, the die is adapted and intended in some cases to form the cap and its flange on the bottle.

Having described my invention, what I claim is- 1. In a machine for fastening caps upon bottles the combination of a die adapted to embrace a bottle-cap seated on and surrounding the bottle-head, mechanism for pressing said die upon the cap on a bottle, means for holding the bottle and die in suitable relation to each other, transversely movable tools adapted to bend separate portions of the capflange into engagement with depressions in the bottle-neck, the intermediate portions of the cap-flange being held against the neck by the die, and mechanism for forcing said tools against the cap, substantially as described.

2. In combination, the main frame, the die, the die-operating frame comprising rods 10, and the transversely-movable tool-bars supported to slide in the main frame, said rods having cams to move the tools, and tool-retracting springs, substantially as described.

3. In combination, a die to press a cap upon a bottle-head, transversely-movable tool-bars to force separate portions of the cap-flange into engagement with the bottle-head, and mechanism for operating the die and tools, said die having side openings to receive the ends of the tools when acting on the cap, substantially as described.

In testimony whereof-I have signed this specification in the presence of two subscribing Witnesses.

PHILIP 'LINDEMEYR.
